Revelation 4:3

4:3 And the one seated on it was like jasper ¹  and carnelian ²  in appearance, and a rainbow looking like it was made of emerald ³  encircled the throne.

Revelation 6:1

The Seven Seals

6:1 I looked on when the Lamb opened one of the seven seals, and I heard one of the four living creatures saying with a thunderous voice, ⁴  “Come!” ⁵ 

[4:3]  ¹ tn Grk “jasper stone.”

[4:3]  ² sn Carnelian was a semiprecious gemstone, usually red in color (L&N 2.36).

[4:3]  ³ tn Or “a rainbow emerald-like in appearance.”

[6:1]  ⁴ tn Grk “saying like a voice [or sound] of thunder.”

[6:1]  ⁵ tc The addition of “and see” (καὶ ἴδε or καὶ βλέπε [kai ide or kai blepe]) to “come” (ἔρχου, ercou) in 6:1, 3-5, 7 is a gloss directed to John, i.e., “come and look at the seals and the horsemen!” But the command ἔρχου is better interpreted as directed to each of the horsemen. The shorter reading also has the support of the better witnesses.
